Title: Centrifugal casting method
IPC: B22D13/10
Filed: 1966-12-14
Abstract: A mould 5 rotating in a water box 1 initially surrounds a pouring trough 8 (with spout 9) as shown and is moved with the box 1 by a cylinder 10, along rails 3, from off the trough as the metal is poured, the mould being progressively lined, just ahead of the advancing metal, with a wet coating of refractory and binder from a fan spray 23 fixed with respect to the pouring trough 8. Before pouring from a tilting ladle 11, a bell end of the mould 5 is coated, after removal of a previous cast pipe, by a nozzle 26 (shown swung out of operative position) a core 15 is then inserted in the coated bell of the spinning mould by an arm 12 operated by a cylinder 18 and shaft 13. After spinning, the core-setting mechanism is withdrawn and the expanding head of a pipe extractor (29), Fig. 2 (not shown), is inserted to grip the cast pipe as the mould 5 and water box 1 are moved back over the pouring trough 8 and off the pipe to allow the bell coating to be applied ready for the next casting. Various positions of the coating nozzle 23 are described, Figs. 4-7 (not shown).

Filed: 1967-08-04
Abstract: Apparatus for determining at regular intervals t, 2t, 3t..., the amount of fluid which has flowed through a pipe line 1 during a given period Nt includes a memory bank 12a, 12b . . . and a distributing device 11 (controlled by a clock 17) to which are fed pulses the frequency of which represents the rate of flow of the fluid and which directs the pulses to each of the memories in turn for a time t, the number of pulses in all the memories being summed in a counter 13, the count in which is read out and printed at the regular intervals t, 2t, 3t... After the count has been read out and before the incoming pulses are fed to a new memory, e.g. memory 12n, the contents of that memory are subtracted from the count and the memory cleared. In the embodiment described, the pulses are derived from a voltage-frequency converter 8 to which is fed a voltage signal the amplitude of which is proportional to the square root of the pressure difference between points 6, 7 on either side of a pressure reducing member 5. The total number of pulses are accumulated in a counter 15.

Title: Method of Construction of Sealed Enclosures.
IPC: G21C3/02
Filed: 1968-05-17
Abstract: In forming a sealed enclosure, e.g. a nuclear fuel element by welding at least one end-cap to a tube, the peripheral surface of the end-cap is formed with a large number of small grooves which when the end cap is inserted in the tube maintains communication between the exterior and interior of the tube, the assembly is positioned in a chamber containing an atmosphere, e.g. a vacuum or inert gas, different from the free atmosphere and the end cap is welded to the tube in such manner as to close the ducts. Grooves may also be formed in the surface of the tube adjacent the end-cap. An annular tapered end-cap 14 is forced between the concentric walls 8, 10 of a fuel element, the walls being of a magnesiumzirconium alloy. Inclined or axial grooves 26 are provided on the inner and outer surfaces of the end-cap, e.g. by milling. Welding is effected by an electron or laser beam in a vacuum chamber. The welding proceeds in a direction such that the inner ends of inclined grooves are sealed first. If an inert gas is to be contained in the fuel element, the welding chamber contains an inert gas, e.g. argon, and gas shielded arc-welding is effected with or without a consumable electrode. After welding, the walls are pressed into grooves 12. Annular or solid end-caps of circular, rectangular and star-shape may be used to seal correspondingly shaped tubes. A refractory insulator 20, of say magnesium oxide, having a grooved periphery may be located adjacent the end-cap.

Title: Electronic anti-theft device
IPC: G08B13/02
Filed: 1968-06-20
Abstract: An anti-theft device for a motor vehicle comprises a transistorised switching circuit designed so as to be responsive both to the setting of a rotary selector contact K4 and to the operation of one or more other switching devices, e.g. ignition switch K1, a switch K2 operated if casing 21 of the rotary selector contact is tampered with, or a switch K3 operated if the vehicle bonnet is opened, completion of a circuit being effected when the rotary selector contact is on any position except a neutral position, which is adjustable, should any of said other switching devices be operated, this circuit energising relays RL1, RL2, contacts r2', r2" and r2"' closed upon operation of the relays completing, respectively, a hold circuit for K4, a circuit for energising an alarm A and an electromagnetic bonnet lock BL, and a circuit by-passing distributor contacts V whereby the vehicle is disabled Each of the switches K1-K3 ap- plies a voltage to the base of transistor T1, switch K1 applying this via a condensor C2 since a switch K'1 operated simultaneously therewith breaks the direct circuit. The resulting voltage at the emitter of transistor T1 energises transistors T3, T4 which switch in the relay RL1 for a time, determined by condensor C3, sufficient for hold contacts r2' to operate. Transistor T2 also applies a voltage to transistors T3 and T4 if a wire F is cut. An alternative normally energised electromagnetic bonnet lock BL' locks the bonnet if the main supply is cut. The switches K1, K'1, K2 and K4 are fitted on a pair of rods 27 secured either directly or, as shown, via a sleeve 34 to a cap 26 which has a plurality of circumferentially spaced projections 23 co-operating with corresponding recesses in the casing 21, the cap being liftable against the action of springs 29 to allow it to be rotated to determine a fresh neutral position for the rotary selector contact K4. The vehicle owner has then merely to adjust a disc K'4 secured to the sleeve 34 until a number corresponding to the setting is opposite a pointer 24, to enable him to start the vehicle by pressing a button 30 operating switch K1.

Title: Colour television picture tube
IPC: H01J29/07
Filed: 1970-09-04
Abstract: In a colour television tube wherein a shadow mask is supported in a faceplate by means of resilient members attached to the mask and provided with apertures which engage studs on the faceplate, the greater thermal expansion and hardness of the members may cause them to deform the studs when they shrink on cooling from the high temperatures employed in processing the tube the rigidity caused by this effect is avoided by making the apertures in the resilient members circular and the studs triangular with rounded apices. The resilient members may be bimetal strips, the strips being joined along their narrow edges and the aperture being provided in the strip having the larger thermal expansion coefficient. The studs are conical and the angle of the cone should preferably be increased from the usual 15 to 20 degrees. As a modification the studs may be secured to the resilient members and the apertures pro - vided in the envelope or in a member secured to the envelope.
